As you can imagine, Rhumbar has pretty good rum based cocktails. We sat on the lounges inside to order our drinks as the patio area was almost full and VERY smoky. The lady bartender was actually quite nice ( somewhat of a rarity for Vegas! ) and even allowed my friend and I to split a Zombie!! She ended up serving us each 3/4 of a cocktail-it was watery but that was great customer service! My rum obsessed husband thought his Mai Tai was good- not quite as good as a real non-touristy Hawaiian Mai Tai, but good for Vegas. It is nicer outside on the patio, especially at dusk when it's not so crowded-they have great music out there!
